This multistandard video IF processing circuit with PLL picture carrier regeneration gives a high performance of linear video demodulation. The IF signal is internally fed via a 3-stage controlled wideband amplifier to the video demodulator and the phase detector. The phase detector pares the phase of IF signal (0°) with the output signal of the VCO (90°) and sets the VCO frequency accordingly.
